This is a great summary, and I agree with everything you mentioned here.

One additional thing to mention though is that Americans are also just richer. Even if you include government benefits (social transfers), Americans rank extremely high on measures of disposable income per household. As far I’m aware that is the most complete measure of income, and despite being a massive country of almost 400 million, the median American is comparable to someone living in Luxembourg.

As you’d expect, this effect only grows when you go up the ladder, and American millionaires are on average richer than say, Danish millionaires.

(Note, I’m not saying that this is good or bad, just that it is. For what it’s worth I think we could learn a lot from the Danish model, but that’s my own distinct, normative option.)

Thus, since there is just generally more capital to go around, capital is easier to raise.

(And as an American, there’s plenty of us here too who enjoy the good life, free of Ferraris and mansions!)
